Webform final update and freeze

Hi, its getting a bit patch busy again so here is my amalgamated patch of the current outstanding issues against HEAD.

This patch includes:

• Minor code conformance issues #18585
• Edit/View data of webforms #18415
• Webform "clear" functionality #18888 by townxelliot
• Results accessible from form #19064
• Webform node deleted without confirmation #19042
• Some minor typographical fixes

Changes affect both webform.module and webform.inc

I recommend that this be the last feature containing patch for 4.5.2 and we start preparing for 4.6.0.

Please advise.
